In short: Intel says AMD’s performance lead with Alder Lake has ended, but it remains to be seen if this will come at the expense of higher power consumption, which in turn will require better cooling. Considering the latest leaks from China, the upcoming 12th Gen flagship processor will be a cutting edge heater even with a slight overclocking of its P-cores.
Intel may unveil its Alder Lake-S processors for enthusiasts as early as next week, but the ongoing stream of leaks is slowly bewildering the hype. The upcoming Core i9-12900K processor has been spotted in a series of benchmarks showing its advantages to the AMD Ryzen 9 5950X processor, but one interesting detail has been overlooked all along – power consumption.
By now, it’s no secret that Intel wants to reclaim the crown of performance in the desktop processor space, losing it to AMD due to the objectively superior Ryzen 5000 series of the latter. Intel CEO Pat Gelsinger recently said that while AMD has managed to gain more consumer and enterprise attention over the past few years, it will soon end with the arrival of Alder lake and Sapphire Rapids.
According to a leak from user Bilibili, who claims to have a qualification sample of the new Intel Core i9-12900K processor, the company decided to create another power-hungry processor in its quest for higher performance.
The Core i9-11900K (Rocket Lake) can already draw up to 307W at full load, but the source claims that the Core i9-12900K can reach 330W at full load when running at 5.2GHz on all eight P-cores while maintaining electronic cores are idle.
It should be noted that this is an overclocking stable only at a voltage of 1.385. The leader also posted a screenshot of the CPU-Z benchmark, which indicates that such overclocking will increase the single-core performance lead that a standard Core i9-12900K should have over AMD’s Ryzen 9 5950X processor to around 31 percent.
We don’t know if the test platform included DDR5 or DDR4 RAM, but the P-cores are expected to have a maximum overclocking frequency of 5GHz, so it’s possible that a standard Core i9-12900K will consume as much power as its Rocket. … The predecessor to Lake, which only has eight P-cores, during heavy workloads.
